If the terminal speed of a sphere of gold (density $\ =\ 19.5 × 10^3\ kg/m^3$ ) is $0.2\ m/s$ in a viscous liquid (density $\ =\ 1.5 × 10^3\ kg/m^3$ ), find the terminal speed of a sphere of silver (density $\ =\ 10.5 × 10^3\ kg/m^3$ ) of the same size in the same liquid ....... $m/s$

A

$4$

B

$0.133$

C

$0.1$

D

$0.2$

Solution

${V_T}\ \alpha \left( {\rho  – {\rho _L}} \right)$

$\frac{{0.2}}{{{V_T}}} = \frac{{18}}{9} \Rightarrow {v_T}\, = \,0.1\,m/s$
